[PATCH 0/2] regulator: mt6363: Fix register access and VEMC voltage handling

[Alexandre Mergnat]

Testing the MT6363 regulator driver showed:
 - the VEMC (UFS VCC) voltage reported as 1.25 V while the PMIC is
   programmed to 2.55 V
 - regmap debugfs showing each register merged with the next one

Reading the code with the datasheet showed more problems:
 - a VEMC voltage change to the misreported value is skipped while
   VEMC is enabled
 - disabling VS2 or a VBUCK rail also clears the enable bits of VS1,
   VS3 and three VSRAM rails
 - the BUCK and TMA key writes also overwrite the two registers after
   each key
 - with hardware trap 1, VEMC voltage changes are not applied and the
   voltage is misreported
